VAPOR-BURNER.

SPECIFICATION forming part of Letters lPatent No. 476,543, dated June'7, 1892.

Application filed July 20, 1891. Serial No. 400,054. (No model) To aZZwhom it may concern:

Be it known that we, JOHN A. LANNERT and WILLIAM R. J EAVONS, citizensof the United States, residingat Cleveland, in the county of Cuyahogaand State of Ohio, have invented certain new and useful Improvements inVapor-Burners; and we do hereby declare that the followingis a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same.

The invention relates to vapor-burners; and the object of the inventionis to provide means for easily lowering and raising the burnerbowl wheninitial starting of the burner occurs and to protect the burner from airdrafts or currents which might cause the flame to flicker and vapor toescape combustion.

The invention therefore consists in the 0011- struction, arrangement,and combination of parts, substantially as shown and described, andparticularly pointed out in the claims.

In the accompanying drawings, Figure l is a vertical central sectionalelevation of the burner in which the bowl is shown in full lines inraised position, as when in use, and in dotted lines as it appears whenlowered for initial starting, so called. Fig. 2 is a cross-section atright angles to Fig. 1, showing fragments of the outer combustion-tubeand the converging inflector and the permanent annular frame supportingsaid parts and the annular frame and attached hood hinged and locked onsaid permanent frame. Fig. 3 is a perspective view, reduced, of thelever and cross-spring thereon for supporting the burner-bowl and thehood-door suspended on its end, and detached from the lever at the rightis the bifurcated weight, which serves as an automatic balance for theparts, as hereinafter more fully described.

A represents what is shown here as an annular rim, which has occasionalinwardly-projecting arms a, connecting with an inner rim or ring A,which at its inner annular edge supports the outer combustion-tube B.The ring or rim A is supposed to be stationary, and may, in fact, beattached to the top of the stove when the burner is secured to thestove, as now generally is the case. This construction affords a freeair-passage between the two parts A and A on the outside of tube 13,

and this open outer space is inclosed by the inflector 0, set upon rimor plate Aat its bottom and converging to the top of the tube B. Theinflector O protects the burner above its base about the combustion-tubefrom aincurrents and compels the air which passes up between the rims AA to feed into the burner or combustion chamber and feed the flametherein.

D is the burner-bowl, which in this instance, and preferably, has anannular form, and is provided with two channels, grooves, or depressionsd d, separated by a rib d as is now well known in this art, and is notset up as novel in this specification. This bowl is supported andadapted to be raised and lowered by the lever E, which has a curvedspring cross arm or bar F, fixed upon its bowed center and engaging thebottom of the bowl, as appears clearly enough in Fig. 1. The lever E ishinged at e to what may be termed a hood G, which is fixed at its upperend to an annular ring or rim H, hinged at one side to the rim or plateA, as h, Fig. 2, and having a small arm or projection 72 with aset-screw 71 at the opposite side to engage the rim A and hold the hoodfirmly thereon. The two parts A and H are normally held together, asseen in Fig. l but when occasion requires the hood and its attachedparts maybe swung down to one side and the inside of the burner madeconveniently available for cleaning or other purposes. Any suitablecatch, lock, or holder may be em ployed in lieu of parts 7t 7L2. Thehood G serves as a support for the lever E, as well as a guard againstair currents or drafts about the center and bottom of the burner, and,with the inflector O, practically incloses the burner about its sides.

The weight of the burner-bowl D and the inner combustion-tube K, as wellas of the hood-door L, is wholly upon lever E, and to counteract andovercome this weight so that the bowl and the other parts will be heldnormally in working position a counter-weight M is provided for the saidlever. This counterweight is here shown as bifurcated or split, so thatit is adapted to pass the brace Nand take the vertical position seen indotted lines in Fig.

Lil

1 when the bowlD is lowered. Otherwise the weight would not be thusdivided. The outer end of lever E is bent to stand at an angle of aboutforty-five degrees to a vertical plane, and has a locking'lug e at oneside to engage a notch in the socket of the shank m of the weight whichfits upon the end of the lever. This lug prevents the weight fromturning. The weight M is made sufficiently heavy to not onlycounter-balance the bowl D and other attached parts when the bowl israised, but to hold the bowl snugly against the rim A, so as to preventair from entering the vapor-distributing chamber in said bowl beneathsaid rim or plate. Yet the difference in weight is not so great that itis not easily overcome when the bowl D is to be depressed for startingthe burner. lVhen thus depressed the counter-weight assumes a verticalposition and rests its weight upon its pivot, so that the bowl willremain down until its position is changed by hand. The weight,furthermore, bears against the frame A H or the hood and serves to limitthe downward movement of the bowl. Then when the bowl is again raisedthe counter-weight not only helps to lift, but holds, the parts inworking position.

0 represents the oil-supply pipe, which has a pen-shaped extremity tofeed the oil to the bowl. \Vhen up, the feed is into the outer channel(Z, and when down the feed is into the inner channel cl upon or aboutthe wick therein, and the lever E, being pivoted at a lower plane thanthe frame A, serves to carry the bowl to one side of the center whendown, so as to cause feeding onto or about this wick, which is now knownin this art. The spring cross-arm F helps to cushion the bowl Dagainst'plate A and to take up any inequalities between bowl and plateabove.

The weight M may be made integral with lever E; but separate parts arepreferred on account of convenience in manufacture and shipping.

By having the weight of the hood G and its attached parts supported fromthe upper frame the weight upon lever E is reduced to the minimum, andthe operation of the burner thereby made easier than it would be if thelever also supported the hood. This also enables the lever to be madelighter than formerly. The hood being permanently suspended from themain frame, access to the bowl when lowered must be provided. This isdone by means of door g, which is fixed on the outer end of lever E insuch position and manner that said door will move with the said lever,and when up close the opening in the front of the hood through which thebowl is reached and the light applied. Any sufficient and suitable meansof fixing the door on the lever may be adopted.

The combustionchamber is surmounted by a flame-deflecting ring Q,extending in this instance wholly over the combustion-chamher, and haslegs or supports g on which it rests and is held above thecombustion-tubes,

thus affording a flame-space between the said ring and the said tubes.This ring has the effectsomewhat of a damper upon the flame, as well asserving to direct or deflect more or less of the flame toward thecenter, thus avoiding a dead place at the center of the bottom of thevessel to be heated, as occurs when an ordinary deflector is used andthe flame is all deflected outward. Above this ring Q is a plate orshield R, of smaller diameter than said ring and having legs -1' restingon the ring Q. This plate orshield is designed, chiefly, to preventwater from dropping or falling into the burner by accident or otherwise,and is not intended as an additional deflector and does not materiallyaffect the action of the flame. It is not therefore essential to theoperation of the deflector-ring, as herein described. A central stem orrod is suspended from this top plate through the lower one into theinner tube, and is stayed laterally by a spider S, resting on the innertube. This stem serves as a guide for said tube when the tube is raisedand lowered. It will be observed that the counter-weight is fixed on thelever, and the word fixed is used in contradistinction to acounter-weight or weight that changes its position on the lever. Hencethough the weight be fixed it may also be detachable, and is shown asdetachable from the lever for convenience in manufacture and shipping,as described. The bottom of the suspended hood is perforated, so as toadmit the requisite volume of air to the burner, and, being otherwiseclosed, prevents untoward ai renrrents from reaching the burner from thebottom.

The peculiar shape of the delivery end of the oil-supply pipe serves twoimportant purposes. In the first place the forward and downward pointanswers as a shield to prevent the vapor from passing directly into thecombustion-chamber when the lighter hydrocarbons are used and there ismore or less vaporization of the oil in the pipe itself, and, secondly,when oil is fed to the bowl instead of vapor the oil runs down thetapering sides to the point or extremity 0, from which it feeds intoeither of the channels (1' or (P, as the bowl is up or down.

In making connection between the counterweight and the lever anyconstruction and arrangement of the parts may be adopted which willthrow the weight on the lever when the bowl is raised and transfer theweight to the pivot when the bowl is down, so that the bowl will remaindown by gravity. Placing the counter-weight at an angle to the lever,substantially as shown, serves this purpose very satisfactorily; yetthis, obviously, is not the only way in which the result can be reached.

Having thus described the invention, what we claim as new, and desire tosecure by Letters Patent, is-
